LOAD -TRIMMER.

SPECIFICATION forming part of Letters Patent No. 688,771, dated December 10, 1901.

' Application filed May 23, 1901.

T aZZ whom it may concern:

Be it known that LJosEPH PATRICK DOYLE, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvementsin Load-Trimmers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in coal-trimmers or devices for equally and evenly distributing coal in loading cars, barges, boats, &c.

The primary object of my invention is to provide a trimmer that can be conveniently swung by the operator to distribute the coal or other material loaded from one end of the car to the other in a simple and efficient manner. In machinery of this class subject to very rough usage the parts should be simple and durable, not liable to break or get out of order, and I therefore have this object in view in the construction which I am about to describe.

Other objects and advantages of my invention will become apparent in the course of the following description, and the points wherein novelty consists will be set forth in the appended claims.

The means wherewith I accomplish the objects above mentioned is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the trimmer, one extreme position of the swinging section being shown in dotted lines, and also the positions of the various cooperating parts are thusshown. Fig.2isafrontelevation. Fig. 3 is a vertical central section clearly showing the manner in which the hinged plates are supported and guided, and Fig. 4 is a similar section taken transversely to that of Fig. 3.

Referring to the drawings, the numeral 1 designates the trimmer, which is constructed in the main of a rigid section 2 and a mov- Serial No. 61,596. on) model.)

able or swinging section 3, both of metal of sufficient strength to stand the strain and wear incident to the use of structures of this character and adapted to be attached to the lower end of the common telescopic swinging spout through which coal or analogous material is ordinarily transferred from one point to another not remote preparatory to transportation. The flange 4 at the top of section 2 is for this purpose. The sections 2 and 3 are preferably rectangular in shape, as shown, and the section 2 is provided near its upper end with brackets 5 and 6, in which and circular reinforcing-plates 6 are supported two short studs '7, one of which has loosely mounted thereon a sheave 8, and the other has similarly mounted thereon a beam 9, which beam is normally in horizontal position, as shown in dotted lines in Fig. 3 of the drawings. This beam has pivotally connected to each of its ends vertical connectingrods 9, (also shown in dotted lines, Fig. 3,) which in turn have their lower ends pivotally secured in the side of section 3 and brackets 10, secured to said section.

The numeral 11 indicates a similar pair of connecting-rods, which have their upper ends pivotally connected to the sheave near its periphery and on opposite sides of its stud.

Integral with two circular reinforcingplates upon the sides of the section 2 are two short depending arms 12, which, together with the said plates, form recesses in which are pivotally suspended links 14, having elongated slots 15 therein for the reception of short headed pins 16, centrally located near the upper edges of the sides of the swinging section 3. These links andpins serve to limit the movement in either direction of the swinging section and assume the position shown in dotted lines in Fig. 1 when the swinging section is swung from normal position.

By reference to Figs. 1, 2, and at it will be noted that the sides of the swinging section overlap the sides of the rigid section for a considerable distance, and the front and rear of said section are cut away to permit it to freely swing with relation to the rigid section, as shown in Fig. 2. The front and rear sides of the rigid section are shown cut away, as indicated by the full zigzag lines, Fig. 2, and dottedlines, Fig. 3. This formation, however, is in no way essential to the operation of the device.

In order that the spaces between the front and rear sides of the swinging section and the front and rear sides of the rigid sections may be practically closed when the lower section is swung and the coal or other material properly guided in its passage through the sections, I provide the plates 16. These plates are hinged at their lower ends by strong hinges 17 to the front'and rear edges of the section 3 and are guided in their vertical movement in guideways 18, which are slightly widened at their lower ends, due to the formation of the guides 18. These strips are firmly secured to the sides of section 2 and, in connection with the corners of said section, form the ways.

In the groove in the sheave and secured therein by a short bolt 19 is a cable 20, which may run to the winding-drum of an engine (not shown) or other suitable means for winding said cable and permitting it to slack or pay out or stop at the will of the operator, as is common in machinery of this class.

In operation the sheave only makes so much of a revolution as is necessary to rock the swinging section to the extreme position, (shown in Fig.1,) which is preferablya quarter of a revolution. Looking at Fig. 1, it will be seen that the cable to the left has been drawn. Thus through the medium of the connections, rods 9 and 11, the sheave, and beam, the swinging section has been moved to the dotted position. The pins 16 near the upper curved edges of the swinging section in this operation will travel in the slots 15 in the links 14 to the ends of said slots, which is the limit of the movement of said section. It will also be noted that'the hinged plates when the lower section is swung out of line with the upper section will assume the position shown in dotted lines, Fig. 1. In loading the car the swinging section, which maybe of any suitable length, ordinarily goes from one extreme to the other and the cable is under such control that the section may be held -for any desired or necessary time in any position intermediate of its extreme position. 1

While the trimmer shown and described is especially adapted for handling coal,ore,and similar rough material, as it is heavily constructed, yet with a lighter construction embodying the same essential features it would be equally adapted for handling cereals, such as corn, grain, or the like.

I claim 1. A load-trimmer comprising a rigid'section adapted to be secured to a loading-spout, rockable members on the rigid section, a swinging section below the rigid section, connections between the two sections whereby the lower section is swung when the rockable members are rocked, and means adapted to be under the control of the operator at a distance from the trimmer to rock the rockable members in either direction for the purpose set forth.

2. A load-trimmer comprising a rigid section, rockable members supported thereon, a swinging section, rods connecting the rockable members and the swinging section,means adapted to be under the control of the operator to rock the said members to swing the swinging section, and means for limiting the movement of the swinging section, substantially as described.

3. A load-trimmer comprising a rigid section, rockable member-s supported thereon, a swinging section, suitable connections between the rockable members and the swinging section, the plates as 16, hinged to the lower section and adapted to operate as described, means adapted to be under the control of the operator to rock the rockable members to swing the swinging section, and means for limiting the movement of the swinging section.

at. A load-trimmer comprising a rigid section for attachment to a loading-spout, short studs mounted on said section, asheave on one stud and a beam on the other, a swinging section, rods connecting the sheave and beam with the swinging section, a cable on the sheave and adapted'to be under the con trol of the operator by which the sheave and beam are rocked and the swinging section swung, and links for limiting the movement in either direction of the lower section, substantially as described. I

5. A load-trimmer comprising a rigid section, rockable members on the rigid section, a swinging section, suitable connections between the rigid and swinging sections, plates hinged to the swinging section, guides in the rigid section for guiding said plates, and means adapted to be under the control of the operator to rock the rockable members on the upper section and thereby swing the lower section, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.

JOSEPH PATRICK DOYLE.
